Are Carver amps compatible with Sda speakers.
In other words can you tie the negative sides of both channels together with Carver amps?

    Is there a particular model you are looking at?
    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
    Thanks

    The only Carver that cannot be used with SDA's is the 500/ 500MT (the one with VU meters).

    Carver TFM-35 and 1.0T both work very well for SRS1.2's. Either one alone has plenty of power to drive them very hard.

    I thought using 2 of either TFM-25's or 35's bi-amped were fantastic, but then I decided to put 2 TFM-55's on my SDA's and now I'm speechless with the results.

I had the speakers originally on a Denon 5700 with 140wpc and I thought that sounded pretty nice, but the Sunfires really opened them up. Thumbs up on the Sunfires.

    To add to Thuffman's list:

    Somebody can correct me if I'm wrong, but I remember reading that the TFM-6CB can be used on SDA's (although they're a little light on power) but they SHOULD NOT BE DAISY-CHAINED!

    I've never tried this, so this isn't first hand info. Just what I've read somewhere (I can't even remember where now).

    I glad to see so many like the Carver amps. A few months ago I asked a question about My SDA 1 signatures and my SDA 2B's and was told on the forum that my TFM 45's would not be enough power for my Polks that I would need to upgrade to more power. I love my Carver SDA combination. Although I am curious as to the ability to run two TFM 45's in mono to each speaker as i was told by many this would be a no go.

    Wow, I am suprised if you were told that here. first off to run any mono block would need a dreadknought or what ever it is called unless you could strap the grounds of the the 45s together.

    Anyway, I have a 45 that ran my SDA1Cs with more than enough headroom. In most cases I could never use more than 80wpc.

    I am running my 1Cs with 40wpc tube amp now and no issues with power.

    I could see where a 45 might not be the perfect amp for 1.2TLs but I do think it would drive them well enough.

    Okay I found what I think you mis-interpreted at http://www.polkaudio.com/forums/showpost.php?p=1171166&postcount=19

    Your poly switches are old and premature tripping. It is not an amp problem. Not sure how you got what you said people told you. In your case I do not recommend removing the poly switches but call Polk for new ones.

    For to drive my SDA-SRS i use 2 Kenwood KM-208 (biamp). The last year i used 1 carver 2x250w hifi model i don't remenber, sound good but very low input volume. After i used 2 nad2400 thx on 4 ohm for to drive them, believe me, the sound was awfull, like crap pro-amp, no spacial effect, no open and warm sound!!!!! then, i use a lot off KENWOOD KM-209,KM-208 for all my home theater setup and the sound is clean, open, warm and i have no headhache at all!! NOW i am AFRAID to spend 1 grand on a mutichannel amp like emotiva.. Realy i don't understand?

    I've been AWOL for a couple years, so excuse me if I'm not up on the new lingo, but I assume that by Dreadnaught you mean the Al-1 connector... The Al-1 eliminates amp ground design considerations.

    I didn't even think about the mono-block Carvers. The Silvers can be strapped to work with SDA’s and the stock interconnect. Not sure about the TFM 75, but I’d bet it’s strap-able as well.

    I don't know the TFM-6CB mentioned above...

    ROFL... That hurt me.... Something says Berlitz Eastern Rim might also work.

    Couple thoughts on the general thread theme developing...
    I spent many happy years with my M-1.5t/ SDA-SRS combo. Then my 1.5 had to go in for repair (Carver Corp was still in the repair biz back then). The repair price included updating my original series 1.5 to the third and final series version. The improvement was startling.... smoother... more open... more detailed.... The experience opened my ears to other possibilities. Then this place blew the lid off...

    Bottom line.... The Carver - SDA combo is good, no doubt about it, and ranks well on any value scale, but there is better. So when you can, as you can afford to, look for better.
